Nursing Elites

1. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.

2. A pregnant client is scheduled to undergo a transabdominal ultrasound, and the nurse provides information to the client about the procedure. The nurse provides which information?

• A. The procedure typically takes 10 to 30 minutes.
• B. She may need to drink fluids before the test and may not void until the test has been completed.
• C. A probe coated with gel will be inserted into the vagina.
• D. She will be positioned on her back, with her head elevated and turned slightly to one side.

Correct answer: B

Rationale: The correct answer is that the client may need to drink fluids before the test and may not void until the test has been completed. For a transabdominal ultrasound, the woman is positioned on her back with her head elevated and turned slightly to one side to prevent supine hypotension. A wedge or rolled blanket is placed under one hip to help her maintain this position comfortably. If a full bladder is necessary, the woman is instructed to drink several glasses of clear fluid 1 hour before the test and told that she should not void until the test has been completed. Warm mineral oil or transmission gel is spread over her abdomen, and the sonographer slowly moves a transducer over the abdomen to obtain a picture. The procedure typically takes 10 to 30 minutes, making choice A incorrect. Choice C is incorrect because a probe is not inserted into the vagina for a transabdominal ultrasound. Choice D is incorrect because the woman is positioned on her back with her head elevated and turned slightly to one side, not specifically on her back.

3. A mother brings her 1-year-old child to the clinic. The child has no record of previous immunizations, and the mother confirms the child has not been immunized. Teaching by the nurse should include which of the following?

• A. Immunizations may be started at any age.
• B. The recommended immunization schedule should be followed.
• C. If a primary series of immunizations is interrupted, it can be continued.
• D. Delaying the start of vaccines does not increase the risk of reaction.

Correct answer: A

Rationale: The correct answer is 'Immunizations may be started at any age.' While there is a recommended immunization schedule, immunizations can be initiated at any age. It is essential to emphasize the flexibility in starting immunizations. The statement 'The recommended immunization schedule should be followed' is too rigid; while recommended, there is flexibility in initiation. Choice C is correct as an interrupted series can be continued without restarting. The statement 'Delaying the start of vaccines does not increase the risk of reaction' is correct. Delaying does not increase the risk of reaction; in fact, it is important to start immunizations to protect the child and the community.

4. A community health nurse is providing information to a group of older clients about measures to decrease the risk of contracting influenza during peak flu season. The nurse should provide which information?

• A. Clients must stay at home and ask a neighbor or family member to run their errands.
• B. It is best to do grocery shopping and other errands early in the morning when crowds are smaller.
• C. Clients should wash their hands frequently and keep hands away from the face, especially during peak flu season.
• D. Drinking eight 8-oz glasses of fluid each day will reduce the risk of contracting influenza.

Correct answer: C

Rationale: During peak influenza season, older clients should take measures to reduce the risk of contracting the flu. The most effective preventive measure is frequent hand hygiene and refraining from touching the face, as this reduces the transmission of the flu virus. While it is advisable to avoid crowds, the direct action of hand hygiene is more impactful. Doing errands early in the morning when crowds are smaller is a good suggestion to reduce exposure but does not address the direct transmission through hands. Drinking enough fluid daily is important for overall health but does not directly reduce the risk of contracting influenza.

5. While a client is on total parenteral nutrition, which of the following values should the nurse monitor closely?

• A. calcium
• B. magnesium
• C. glucose
• D. cholesterol

Correct answer: C

Rationale: Glucose should be monitored closely when a client is on total parenteral nutrition due to the high glucose concentration in the solutions. Monitoring glucose levels is crucial to prevent complications such as hyperglycemia or hypoglycemia. Calcium and magnesium are usually monitored to assess electrolyte imbalances, while cholesterol levels are not directly impacted by total parenteral nutrition. Therefore, choices A, B, and D are not the primary values that need close monitoring during total parenteral nutrition.
